Abstract

PURPOSE

The purpose of this study was to compare asymmetric mandibular prognathism individuals with symmetric mandibular prognathism individuals using a new alternate spherical coordinate system.

MATERIALS AND METHODS

This study consisted of 47 computed tomographic images of patients with mandibular prognathism. The patients were classified into symmetric and asymmetric groups. Mandibular and ramal lines were analyzed using an alternate spherical coordinate system. The length as well as midsagittal and coronal inclination angle of the lines was obtained. The bilateral differences of the spherical coordinates of the facial lines were statistically analyzed in the groups.

RESULTS

There were significant differences between the groups in bilateral difference of the length and midsagittal inclination angle of the lines (p<0.05). The bilateral difference of the length and midsagittal inclination angle of the lines has significant correlation with chin deviation (p<0.05).

CONCLUSION

The new alternate spherical coordinate system was able to effectively evaluate facial lines. The bilateral difference of lengths and midsagittal inclination of the facial lines might contribute to the facial asymmetry in mandibular prognathism individuals.

摘要

目的

本研究的目的是使用一种新的交替球坐标系比较不对称下颌前突个体与对称下颌前突个体。

材料与方法

本研究包括47例下颌前突患者的计算机断层扫描图像。患者被分为对称组和不对称组。使用交替球坐标系分析下颌线和升支线。获得线的长度以及矢状面和冠状面倾斜角。对两组面部线球坐标的双侧差异进行统计学分析。

结果

两组在面部线长度和矢状面倾斜角的双侧差异上存在显著差异（p<0.05）。面部线长度和矢状面倾斜角的双侧差异与颏部偏斜有显著相关性（p<0.05）。

结论

新的交替球坐标系能够有效评估面部线。面部线长度和矢状面倾斜的双侧差异可能导致下颌前突个体的面部不对称。
